If you are still having a problem with mealy bugs. Get some Bear Advenced from lowes. Rose and flower spray. Do not get the one with fertilizer just the bug spray. It contains merrit and is a systemic spray that works good on mealys and scale. It is also good for wasps. I hit a wasp with a spray and it is on the ground convulsing and dyeing quickly. It is the same stuff that is in frontline for dogs so it is safe to use indoors.
